• Aortic Coarctation—Adult

    (Coarctation of the Aorta—Adult)


    The aorta is the main artery carrying oxygen-rich blood from the heart to the body. Aortic coarctation is the narrowing of the aorta which slows or blocks the blood flow. It is often associated with other heart and vascular conditions, like abnormal heart valves or blood vessel outpouching. These conditions carry a risk of additional future problems.
